Put the spaetzle in plenty of boiling salted water and cook for about 16 minutes. Stir occasionally. In the meantime clean, wash and cut the pointed cabbage into strips. Clean and halve the mushrooms. Heat 20 g fat in a frying pan, add cabbage and steam for about 5 minutes while turning over high heat.
Season with salt, pepper and nutmeg and remove from the pan. Heat 25 g fat in a frying pan, fry the mushrooms lightly while turning and deglaze with stock. Bring to the boil, remove from the heat and stir in crème fraîche. Season with salt and pepper. Pour spaetzle onto a sieve and drain well. Put half of the spaetzle into 4 greased, ovenproof moulds and sprinkle with 100 g cheese. On top of each of them add steamed pointed cabbage and mushrooms with cream sauce. Spread the rest of the spaetzle on top and sprinkle with 100 g cheese. Gratinate in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for about 10 minutes. In the meantime, peel onions and cut into fine rings.
